Alexa Ray Joel wants everyone to know that her supermodel mom, Christie Brinkley, is not to blame for her depression-related episode on Dec. 5, when she had to be hospitalized.

She says, “My mom & dad [famous singer Billy Joel] are my role models and best friends. What I was struggling with had nothing to do with them. The press was particularly harsh on my mother, which is unthinkable to me, because she is the kindest woman I’ve ever known.”

Christie’s ex-husband Peter Cook had said that Christie and 24-year-old Alexa often fought about appearance and weight, but Alexa countered those accusations on her Facebook Page, “Consider the source.”

Alexa says that the REAL reason she took more than the recommended amount of homeopathic pills, which led to hospitalization, was because she was suffering from “heartbreak-related depression.”

“Although it does not get much attention in our society, it is a very serious and painful condition that often gets swept under the carpet. I hope to bring this topic more to life.” —Corynne Steindler
